49ers-Seahawks draws record-breaking eyeballs

While much of Sunday's defensive battle between the 49ers and Seahawks was hard to watch -- particularly for San Francisco fans -- that didn't stop the eyeballs from staying glued.

The game drew an average of 20.5 million viewers on NBC, making it the most-watched primetime NFL matchup between West Coast teams in nearly two decades.

The 29-3 Seahawks win on Sunday Night Football also drew 1 million more viewers than the Week 16 matchup of the same two teams on Sunday Night Football last season.

The last most-watched primetime NFL game between two West Coast teams? It happened on Nov. 27, 1995, pitting the defending-AFC champion San Diego Chargers and the rival Oakland Raiders. That game averaged 21.6 million viewers.
